Do you know how to fix a screen that looks like this?

I posted that Firefox messed up Achaea by disabling some plugins, but I checked up on the plugins and I'm not so sure they're related to the game. This is what my screen looks like. It's awkward, but I can find and place the mini-windows in an approximation of where they were, but I've no idea what to do about the mapper. I am working with other clients, but I'd like to get Nexus working the way it was - it has a lot of nice features.
